Esu Rotsino was a female senator who represented the agricultural planet Abrion Major in the Senate of the Galactic Republic. In 22 BBY, during the Separatist Crisis, due to her planet's ag-producers living for years with minimal options and control of the goods they provided, Rotsino led the entire Abrion sector to defect from the Republic to the Confederacy of Independent Systems. In her Articles of Secession to the Senate, Rotsino explained that the sector felt that the Separatists were a more appreciative market to their products, and that they wished to be freed from the bureaucracy of the Republic. As a result of her actions, many Republic planets began to plea to the Senate for aid, as their food supplies had come from the Abrion sector.
